Herbert Spencer

Died 8 Dec 1903 at age 83 (born 27 Apr 1820). English sociologist and philosopher who was an early adherent of evolutionary theory. He regarded society as an organism which was evolving from a simple primitive state to a complex heterogeneous form according to the designs of an unknown and unknowable absolute force. Similarly, knowledge developed from an undifferentiated mass into the various separate sciences. Formulating his ideas independently of Darwin, Spencer coined the phrase “survival of the fittest” as early as 1852. He applied Darwin's theory of natural selection (proposed four years later) to social development and in A System of Synthetic Philosophy (1862-96) presented a philosophical system to the natural and social sciences, synthesizing metaphysics, biology, psychology, sociology, and ethics.
